Hence for a desired message of 10 bytes, a VALUE code of zero (00000000 ) is entered.
For the maximum length of 520 bytes, a MESSL code of 255 (11111111) is entered. The
default message length is 520 bytes.
1.1.4 Serial Data Rate
PARAM = 0 1 0 0 Default = 0 0 0 0 1 0 0 0
To select or change the serial data rate, enter the following VALUE code. The serial data
rate can be different at different 405U modules in the same system. The default value is
9600 bits/sec.
Serial Data Rate VALUE
(bits/sec)
1200 0 0 0 0 0 0 0 0
2400 0 0 0 0 0 0 0 1
4800 0 0 0 0 0 0 1 0
9600 0 0 0 0 0 0 1 1
19200 0 0 0 0 0 1 0 0

Serial Data Rate VALUE
(bits/sec)
57600 0 0 0 0 0 1 1 0
115200 0 0 0 0 0 1 1 1
1.1.5 Radio Data Rate
PARAM = 0 1 0 1 Default = 0 0 0 0 0 0 0 1
To select or change the radio data rate, enter the following VALUE code. The radio data rate
should be the same at each 405U module in the same system. The default value is 4800
bits/sec.
Radio Data Rate VALUE
( bits/ sec)
19200 0 0 0 0 0 0 1 1
57600 0 0 0 0 0 0 1 0
Radio Data Rate VALUE

1.1.6 Transmit Hold-off Time
PARAM = 1 1 0 0 Default = 0 0 1 0 1 0 0 0
A delay time may be configured such that the 405U unit will not transmit during the hold-off
time after transmitting a previous message. The maximum hold-off time is 255 msec. The
transmit hold-off time value is the 8-bit binary equivalent of the desired time in 1 msec
increments. Hence for a desired hold-off time of 10 msec, a VALUE code of ten (00001010 )
is entered. For the maximum time of 255 msec, a VALUE code of 255 (11111111) is
entered. The default tail time is 40 msec. Appendix B lists the 8-bit patterns for each value
between 0 and 255.
